Purple coralline is slowly turning white ???

[Sanchez2896]

Not sure why this is happening ... Normally super bright but now seems to be turning white

 

[noelskii]

It's dying...

Check your levels. Conditions are likely not optimal for coralline growth, like they were before.

I switched from dosing kent calcium to kent purple up

 

[NYreefNoob]

Purple up sux, check your levels but bet alk is low

 

[Reefseas]

It's def dying, stick to kent. Always have better results with my kent calcium.

 

[nanoreefer22]

Dose some b-ionic instead. Don't waste time with those other products.

 

[ReefWreak]

Do you have corals? Do you dose alkalinity with your Kent calcium? Are you testing your calcium and alkalinity?

If no to the above, then waterchanges should be enough to keep coralline algae happy. If you do have some corals, then it might be worth getting your calcium and alkalinity checked out, and balancing the two, then adding kalkwasser to your top-off water to keep the balanced levels up going forward in an inexpensive and easy way.

To the OP of the thread, do you have a quality Alk, Cal, Mag test kit ( i use red sea pro ). Also what are your other levels such as salinity, temp, phosphates ect....

To matt im sending you a RB

 

[ohana888]

do you have an urchin who's eating it and cleaning it off your rock???

do you have an urchin who's eating it and cleaning it off your rock???

I have an urchin that eats it but that won't make it turn white. Most likely the alk is low.

Idk my alk running steady 8 and not getting it I used to get more when I was topping off with kalk water
